One thing that I haven't seen discussed that much is if having the full group with you at the end is a good idea.
Will going alone and leaving the group at the boat cause their untimely demise as the hoard overruns them. Or will it leave them in safety as the sit on the water waiting.
Will taking a full group just slow you down and cause more death. Or will it make you a well oiled rescue machine.
I honestly think the group at the end of episode 4 will be dead or permanently separated from Lee about halfway through the chapter. Whether they come with you or not will just determine if they either die or "escape"
